What Are Groundwater Management Areas?
Groundwater management areas were created "in order to provide for the conservation, preservation, protection, recharging, and prevention of waste of the groundwater, and of groundwater reservoirs or their subdivisions, and to control subsidence caused by withdrawal of water from those groundwater reservoirs or their subdivisions, consistent with the objectives of Section 59, Article XVI, Texas Constitution, groundwater management areas may be created..." (Texas Water Code §35.001) Added by Acts 1995, 74th Leg., ch. 933, §2, eff. Sept. 1, 1995.
The responsibility for Groundwater Management Area delineation was delegated to the Texas Water Development Board. (Section 35.004, Chapter 35, Title 2, Texas Water Code)
The initial Groundwater Management Area delineations were adopted on December 15, 2002, and are modified as necessary according to agency rules. (356.21, TWDB Rules)
There are 16 groundwater management areas in Texas. All groundwater conservation districts are part of at least one groundwater management area.

Proposed DFCs
Desired Future Conditions (DFCs) are the long-term groundwater management goals that describe how much groundwater levels are expected to decline over a 50-year planning period. These goals help guide groundwater management and are used by the Texas Water Development Board to calculate the amount of groundwater that can be produced while supporting long-term water planning.
The proposed DFCs for the aquifers within the Lost Pines GCD in 2080 are:
What Are Desired Future Conditions?
Desired future conditions are defined in Title 31, Part 10, §356.10 (6) of the Texas Administrative Code as "the desired, quantified condition of groundwater resources (such as water levels, spring flows, or volumes) within a management area at one or more specified future times as defined by participating groundwater conservation districts within a groundwater management area as part of the joint planning process." The specified time extends through at least the period that includes the current planning period for the development of regional water plans pursuant to Texas Water Code §16.053, or in perpetuity, as defined by participating groundwater conservation districts within a groundwater management area as part of the joint planning process.
